Preface
Thanks for choosing our softener series products. These products are featured by good
softening effects, stable performance, excellent appearance, compact structure and simple
handling, etc. They can meet the soften water demand if family washing, bathing,cleaning and
boiling, etc. Besides, they also can be applied to supplying high quality soften water for
institutions, schools, group companies, and so on.
1. Product Profile
The product is working automatically and intelligently, it adopts food-grade cation resin to
soften water with characteristics of big flow rate and good softening effect, efficiently reducing
calcium and magnesium ion content of tap water. After the resin is saturated, the regeneration
function will automatically control the product to brine and conduct regeneration, recovering the
softening function of the resin. It can automatically realize the function of backwash, regeneration,
brine refill and fast rinse without manual operations.
2. Working Principle
Ion exchange technique is applied to the softener. It can realize the purpose of wiping off the
lime scale (Calcium carbonate and magnesium carbonate) through replacing the calcium ion and
magnesium ion by the sodium ion of the resin. According to the pre-set program, it can
automatically control the open anad close of each valve, so as to conducting softening,
backwash, regeneration, slow rinse, brine refill and fast rinse.

7. Regeneration mode is meter delayed type:
Regenerate on the day although the available volume of treated water drops to zero(0).
Regeneration starts at the regeneration time. It can avoid the shortage of water for regeneration.
8. Working automatically:
Softening: Under a certain pressure and flow rate, the raw water flow through the product,at the same
time, the calcium ion and magnesium ion of raw water are replaced by the sodium ion of resin, reducing
the content of calcium ion and magnesium ion and realizing the purpose of softening water.
Backwash: After the resin is saturated and lose softening efficacy, the program start backwashing before
regeneration. On one hand, it can wipe off the broken resin and the impurity on surface layer of resin.On
the other hand, the reversed flow direction can loosen the tight resin and make it benefit for the touch
between resin particle and regeneration liquid.
Brine and slow rinse: A certain concentration brine flow through the resin.Meanwhile, the calcium ion
and magnesium on the resin surface layer are replaced by the sodium ion, making the invalid resin
regeneration and recovering its softening capacity.
Brine refill: The brine tank is refilled with water to dissolve the salt so as to provide the saturated brine
for next regeneration.
Fast rinse: Discharge the residual brine and compact the resin particle so as to reach the best
softening effect. By this step, the product automatically finished one service cycle.
5. Application
The product can be used for treating the tap water or other qualified raw water.

7.2 The Installation and Usage of Brine Valve
The brine valve plays two roles in the whole system: First, under the brine and slow rinse status, with the
floating ball, the brine valve can prevent the air from being inhaled which may affected the regeneration
and usability. That is, the brine valve has the function of air check. Second, under the brine refill status,
the brine valve can control the volume of refilling water by controlling the position of floater.
7.3 The Installation and Usage of Bypass Valve (Optional)
The valve has the function of bypassing. When the piston is pushied to the position of inlet and outlet,
the valve is in service status; When it is at bypass position, the valve is in bypass status.It adopts quick
joint structure to connect he valve with bypass valve, with the characteristics of reliable sealing, quick and
convenient installation.(Refer to the below pictures)

7.4 The operations of the Valve with The Function of Mixing Water
If the users think the hardness of outlet water is too low, they can adjust the hardness by using the
function of mixing water according to the actual demand.
Operation: Anticlockwise rotates the adjusting bolt (As the picture shows.) The wider angle is, the
higher outlet water hardness will be.
8. Usage Illustration
After installing the device and setting the relevant parameters,please conduct the trial running as
follows:
※Fill the brine tank with the planned regeneration salt and the water(Refer to the below table), making
the brine is saturated(26%). Then start the device (This step is necessary only for the situation that the
device is put into use for the first time.)
Resin Tank 0713 0717 0815 0817 0917 1017 0835 0935 1024 1035 1044
Water(L) 3 4 4.5 5 6 7 9 10 9 13.5 15
※ Switch on power. Press" " and go in the Backwash status. Slowly open the inlet valve to 1/4
position(Avoiding to open the valve too quickly to damage the device and make the resin run off). At
this moment, you can hear the sound of air-out from the drain pipeline. After all air is out of pipeline,
then open inlet valve completely and conducting 2-3 minutes backwash, cleaning the foreign materials
in the resin tank until the outlet water is clean.
※Press " " turn the status from Backwash to Brine& Slow Rinse. Under this status, the brine will be
absorbed from the brine tank into the resin and the resin is regenerated. After absorbing, the brine
valve will close. The system will still conduct about 15 minute's slow rinse, wiping off the residual brine.
The whole process will take about 40 minutes to finish.
※Press " " and turn into Brine Refill status. The brine tank will be refilled with water to dissolve the
salt. When the level controller reaches the required height, the refilling will be stopped. The new
saturated brine will be used for next regeneration.

※If the raw water fails to meet the standards of local tap water, such as the sediment concentration or
residual chlorine content exceed the stand,etc., the pretreatment device should be installed before the
device.(Such as Y type filter, ultra filter, and so on.)
※During the operation, please check the brine tank regularly to ensure there is brine in the tank. And
when adding brine, please make sure that salt level is higher than water level(see picture I). When the
salt level is lower 1/3 of water level(see picture II), please add in time. (Attention: Make sure the
dissolving salt time is more than 6 hours so as to make the brine saturate)
※Please strictly use the salt of more than 99% purity only. Any salt with additive or large particles is
forbidden to add.
※Please use this product under the water temperature between 5-45 ℃, water pressure 0.15-0.6MPa.
Failure to use this product under such conditions voids the warranty.
※Sodium used in the water softening process should be consideered as part of your overall dietary salt
intake. Contact doctor if you are on a low sodium diet.
※Without being used for a long time or the pressure of the inlet water is instable, please close the inlet
port and turn off the power. Before using again, please firstly conduct a regeneration cycle through
manual operation so as to ensure the quality of soften water.
※During the service of product, prevent water hammer happened. Do not make these operations, such
as quickly and fully opening valve, or quickly and fully closing valve or shut off water pump,etc.
※If the water demand is increasing(Compared to usual demand) or the hardness of raw water is rising,
please reduce the regeneration cycle and increase the regeneration times, ensuring the soften water
yield.
※When use the softener for the first time or the device is idle for long period, it is normal that the outlet
water is yellow. Please put into use after 2-3minutes' rinsing.
※Sometimes the brine in the brine tank will forms salt bridge. That is, there is a space under the brine
which prevents the salt from being dissolved and hinders the resin regeneration. It is suggested to check
regularly. If there is salt bridge, please mash it.
※During regeneration period, there is no softened water for using. But if it still need water for using, it is
not suggested to bypass big quantity of hard water, it may affect the regeneration efficiency.
